CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 453,670, dated J une 9,1891.

Application filed March 14,1891. Serial No. 385,087. (No modehl To allwhom, it may concern:

Be it known that we, TALTER LINCOLN ScHLAe-ER and JOHN C. DOMMERMUTH,citizens of the United States, residing at Avoea, in the county ofLuzerne and State of Pennsylvania, have invented a new and usefulCar-Ooupliug, 0f which the following is a specification.

This invention relates to car-couplings, and more especially to thatclass known as drawbars,7 and the object of the same is to producecertain improvements therein.

To this end the invention consists of the de' tails of constructionhereinafter more fully described and claimed, and as illustrated on thesheet ot' drawings, whereiny Figure l is a plan view of this device withthe car-body removed. Fig. 2 is an end elevation showing the uncouplingdevice. Fig. 3 is a horizontal section through the draw-bar anddraw-head. Fig. et is a perspective detail ot' the yoke-strap. AReferring to the said drawings, the letter C designates a car, beneathwhich are arranged the guides Gfor the draw-bar B. Between these guidesare located plates P,whose movements are limited by shoulders or blocksK, and through these plates extends a rod R, having a nut N at its rearend standing against the back face of the rearmost plate and connectedat its front end with the rear end of the draw-bar B, which standsagainst the front face of the front plate. 'Upon this rod R between theplates is located a strong coiled spring S. rlhis spring cushions theblows received in coupling, when the drawbar B will be driven to therear, and it also cushions the drawing-tension, all in a manner whichwill be clearly understood. The drawbaris supported by ayoke-strap Y.(Best seen in Fig. 4, but shown in dotted lines in Fig. l.) This has. arecess Y', which embraces the draw-bar and prevents its lateral play.

The draw-bar B has a cavity V in its body with a rounded rear end E, andthe front end of this cavity opens through a portion of the face of thedraw-bar, the outer side O of the opening standing behind the draw-headand the remaining portion F of the face being slightly dished, as shown,fora purpose to appear hereinafter.

The draw-head II is hook-shaped, the shank thereof extending into thecavity of the drawbar and heilig mounted on a vertical pin Q. therein,so that its rear end shall rest against the rounded end E of the cavityand the pins will not entirely sustain the shocks of coupling. The headof the hook-shaped drawhead is cut away, as at A, and a verticalpinopening .I intersects the saine, whereby an ordinary link may becoupled in this drawhead, as will be readily understood. The body of thedraw-head moves within the opening in the front end of the draw-bar andat one side of the face F, and a leaf-spring L is connected to thedraw-bar and bears at its free end upon the outer side of the draw-head,preferably at a point within the outer side O of said cavity, the normaltension of this spring pressing the hook-shaped draw-head inwardly, aswill be seen. It' desired, several leaf-springs maybe used withoutdeparting from the spirit of our invention.

V is a vertical rod journaled in eyes I in the end of the car and havinga handle II at its upper end and a crank C atits lower end, and Ndesignates a chain connecting this crank with the outer side of thehooked front end of the draw-head. Then the crank is operated by the'turning of the handle from the top or platform ot the car, this chainwill be drawn upon to lnove the drawdiead II against the tension of theleaf-spring L, and hence to uncouple the cars; but the outer side O ofthe opening in the front end of the draw-bar willlimit the movement ofthe drawhead to only so much as is necessary in the operation ofuncoupliug.

lVhen the cars are to be uncoupled, they are brought together, and thebeveled or rounded faces of the two draw-heads II will slide over eachother, causing the leaf-springs L to bend outwardly slightly. The frontends of the draw-heads will strike the faces F of the draw-bars, and thelatter will be driven to the rear against the tension of the coiledsprings S, the draw-heads meanwhile springing into engagement with eachother. The uncoupling can be done in themanner stated above.

What is claimed as new is- The herein-described car-coupling, the sameIOO comprising a draw-bar B, having a cavity V, opening from its frontend and provided with a rounded rear end E, the outer side O of thefront end of said cavity being closed and the opposite side F of the endof the draw-bar being solid, a draw-head H, having a hooked front end,its shank extending into said cavity and having a rounded rear end:resting against said end E of the cavity, a Vertical pivot-pin Qthrough said shank concentric with said rounded end, aleaf-springsecured to the draw-bar With its front end standing Within the openmonth of said cavity and pressing against the back of said draw head,
